Running a Warthog CNC router with Mach 3. Have Featurecam and have discovered that I needed a post processor file(s) to allow Mach 3 to deal with the Featurecam generated drawings and toolpaths. Found the post processor file (standard not metric) .....now... what do I do with the post processor file? Where does it get placed ....installed... or whatever?

When you save the toolpaths in FeatureCam I would expect to get a prompt to select the postprocessor.

BTW I'm not familiar with FeatureCam.

The file you want will be something like this, C:\Program Files\FeatureCAM\M-LBRY\INCH after you place it there you can open it by clicking the tool bar at the bottom right, the 2nd box from the right. Then you can choose the settings for your machine and edit the post to meet your needs.
